Specification forming part of Letters Patent No. 169,331, dated November2, 1875; application led June 15, 1875.

To all whom t may concern Be it known that I, CHARLES J. APPLE- TON, ofPhiladelphia, State of Pennsylvania, have invented a new and ImprovedKnitting- Machine; and I hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, making a part of this speciflcation, and theletters of reference marked thereon, in which the same letter representsthe same thing in each figure.

This invention relates to certain improvements in knitting-machines; andconsists of through the center of Fig. 1.

Referring to the drawings, A represents the welt-cam, B, the ratchet; C,the patterncam; D, the shaft for pulleys l 2 3 4; E, the Welt-lever post5 E', the spring-welt lever 5 F, the driving-gear; g, the catch and dog;H, the dial-ring, J, the cam-ring; K, the needle-cylinder, M, the Ybracet'o hold cap and dial; N, the cap; O, the dial; P, the collar on shaft;g, pin to move slide R; S S, the slide-boxes; S', the ratchet-pawl towork ratchet B, T, the spring on shaft D 5 U, the bed-plate; V V, thepillars holding brace M5, W, the collar working against cam C; K X, theshaft-lugs Z, the ratchet and' cam-shaft; Z', the belt-shifter.

One object of my invention is to produce, at the same time, two stripedknit fabrics with selvage sides, of any desired pattern, on a circularknitting-machine, with a single feed for each fabric, the fabrics beingsimilar to hand-loom Work. Another object is to produce Welts on eachfabric, automatically, at pleasure.

I accomplish these objects by giving the cam-ring an oscillating as Wellas at times a circular motion.

On a section of the needles in the cylinder and dial yarn of one coloris placed, and on another section yarn of a different color, and theyarn changes sections at determined revolutions of the cam-ring, so thateach section of needles knits rst one color and then the other.

The operation of the machine is as follows: The Workbeing on theneedles, shaft D turns gear F, which revolves cam-ring J until pin gstrikes ,slide R, which moves belt-shifter Z', so that the open belt ontight pulley l is moved upon loose pulley 2, and the cross-belt on loosepulley 2 is moved upon tight pulley 3, and cam-ring J is therebyreversed, and revolves in the opposite direction until pin q strikesslide B.. rlhe cam ring J continues to revolve back and forth, asdescribed, until slide R, by pawl S',"moves ratchet B on shaft Z, so asto cause pattern cam C to push against collar W and move the pulleys onshaft D at the same time that slide B moves the belts in the samedirection. The belts are consequently not shifted, and cam-ringJ makesan entire revolution before itv is reversed, moving the yarn of onecolor upon the section of needles previously occupied by the othercolor.

The welt-producing mechanism acts thus:

' The welt-cam A on shaft Z, moved by ratchet B, depresses the inner endof lever E' by lifting the other end, so that the inner end strikes thedog and catch g, detaching dial-ring H from the cam-ring J, so that thedial-needles cease to work, and plain knitting is done by theA needlesoperated by cam-ring J until dog gag-ain enters its catch on dial-ringH, when the dial-needles Will be again thrown into action, and both setsof needles will knit, the plain knitting having formed the Welt.

The action of the needles is the same as in vthe Pepper and other ribbedknitting-machines.

What [claim as my invention, and desire to secure by Letters Patent, is-

1. The combinatiom'with the needle-cylinder K and dial O, of thecam-ring J and dial-ring H, constructed substantially as described, sothat ribbed or plain work may be produced automatically, at pleasure, asset forth.

2. The, combination of a. cam-ring, J, slide l 1?., 1pulleys1 2 3 4, andlpattern -cam C, 'mlapted to Operate together, substantially asdescribed. `Y

3. Four sliding pulleys, alternately tight and loose, applied to a.shaft, D, and coulbined with shifting mechanism, as described,

whereby circular and semicircular movements maybe imparted tothe'cmfriug J, et `pleasure, substantially as specified. Y o
